I use a cylinder stove. It's a military stove that has been converted to wood. They are great. It heats a 10x20 tent real quick, and keeps it warm. The only time I have used the stove is in April, May, and November, when temps are down. I will be using it again next weekend. If you are lookin for one of these, send me a PM. I know where you can get 'em....
